Part 9

ANSI A300 (Part 9) - 2011 Tree Risk Assessment

“State forestry agencies support local programs to inventory public trees in a wide range of settings – from street trees to trails to wooded parks. Managing risk for those public trees is ‘Job 1’ for city tree managers and the new ANSI standard for tree risk assessment helps state and local governments define appropriate methods and work plans for getting this work done.” - Pete Smith, Partnership Coordinator with the Texas Forest Service-Urban Forestry Program

This part of the A300 standards is the first national standard to address risk assessment of trees. Part 9 Tree Risk Assessment  addresses:

  • Tree structure assessment practices, including:
  • Levels of tree risk assessment
  • Target identification
  • Risk analysis and reporting
  • Owner determination
